Well...the idea that something from space was totally ignoring the humans and communicating with the whales is a nice plot line, and one I wish could be explored more fully.
Like...
- Did the probe just like the whales?
- Pretty songs, need more. No more? Ok, I -the probe - make planet go whoosh?
- Whales are remnants of a civilization we have no trace of and it knew that? (Shades of Distant Origin)
- How the heck could it even HEAR the whales? That puts all sorts of plotlines out there (Are there sensors on Earth? Infrasound has a further effect? The probe had crazy tech? Something else?)
I'd just like to, some day, see the probe explored the way the planet killer Doomsday Machine has been.
